90 BULLETIN OF THE 
track of the last locality known as the ‘‘ Woods Schoolhouse.” The 
schoolhouse of the name has disappeared, for its foundations only remain ; 
but the explorer can readily find his way to the spot by passing from the 
new schoolhouse on the Cedar Tree Neck road westwardly along the ser- 
pent kame, the only deposit of this nature on the island, until he passes 
a stone wall, a little to the west of which, in the roadway and on the 
bare ground thereabout, he may find an abundance of fragments of this 
peculiar sandstone. Circumstances prevented my undertaking any care- 
ful study of this place until seventeen years after its discovery. In 1887 
I returned to the locality, and with the help of my assistant, Mr. Foerste, 
undertook a careful collection of the abundant fragments which I found 
at this point, as well as a systematic study of all the area of the island 
which gave promise of affording similar material. The search for other 
localities was fruitless, and as this is the only one on the island which 
has afforded fossils in condition for identification, I shall hereafter limit 
my account of the bed to what is exhibited at this point. 
As is shown in the accompanying section, the Cretaceous fragments 
found at this locality occur only within a small area. They have been 
found over a surface having an east and west extension of about 300 
feet, and a north and south length of about 200 feet. ‘The position is 
immediately to the south of a shoved moraine, whieh extends up to and 
probably includes this part of the drift accumulations. In this area, 
from the surface to the depth of four or five feet, or as far as the exca- 
vation penetrated, by far the larger part of the fragments are composed 
of the deposit in question. The rock consists of a very coarse sandstone 
abounding in quartz pebbles, containing indeed little other material save 
quartz fragments from an inch in size downward. The largest of the 
fragments containing fossils are about three feet across and a foot thick ; 
the greater part of them are extremely angular, showing by their form 
that they have been transported for a very short distance. Moreover 
the extreme softness of the material would make it impossible for it to 
endure any distant ice carriage. The sand in which the fragments con- 
taining fossils were embedded appears to be to a great extent derived 
from the destruction of the same rock. This fact is indicated not only 
in the physical aspect of the sands, but in the character of the vegeta- 
tion which grows upon them. Generally, in this morainal district, the 
decomposition of the pebbles containing large amounts of feldspar and 
mica affords a moderately fertile soil, which maintains grass. In the area 
where these fragments abound, the sand is evidently far more siliceous 
than elsewhere in the area of the moraine, and is too lean to support
